One inspiration I got from Bosman&#39;s book is &quot;generalized Yin Yang&quot;. You can subdivide the circle into parts that have both equal area and equal circumference. The lines defining the subdivisions are all circle segments with integer relative diameters. The Yin Yang is a powerful symbol. The rainbow is also often used these days to symbolize diversity. I was quite pleased with the possibility of combining these 2 symbols.

@GerardWestendorp@mathstodon.xyz in the usual yin-yang symbol there's also a spot of yan in the ying and vice versa. With an order-7 version of the same thing I suppose you'd want a spot of _every_ colour in every other colour. (If nothing else, if you want to use it as a symbol of diversity, the idea that "there's always a little bit of $this_category in $that_category" seems likely to raise the blood pressure of anti-diversity people, which is surely a feature rather than a bug.) In the order-2 symbol the natural place to put each opposite-coloured spot is to make it a small circle centred in the larger circle. I don't know if there's any particularly 'nice' layout for the spots in the order-7 symbol. Your construction lines divide each region into _seven_ parts, not six. Placing the spots might have to be done by art rather than mathematics. But at least there's the extra resonance that the total number of spots would be 42.

@GerardWestendorp@mathstodon.xyz A while back I got inspired by this, and found that you can divide polygons into equal sized subdivisions. I didn't prove i can always do it, but here are a few examples...
